“I’ve had a wonderful six years leading this amazing bunch of people and now feel it is time for me to look for a new entrepreneurial challenge,” Southgate said in a statement. “I want to thank everyone at Shed and Warner Bros., and wish them all the best for the future.”

Shed Media, one of the U.K.’s largest and most prolific production companies, includes divisions Wall to Wall, Twenty Twenty Television, Ricochet, Watershed Television, Renegade Pictures, Yalli and Headstrong Pictures.

Warner Bros. Television Group president and chief content officer Peter Roth, Warner Bros. Worldwide Television Distribution president Jeffrey R. Schlesinger and Warner Bros. Television Group Business and Strategy president Craig Hunegs released the following joint statement:

“With the completion of the full acquisition of Shed Media Group, we are excited to operate the company now under the Warner Bros. brand as a fully integrated part of the Warner Bros. Television Group. Nick and Claire, with their shared experience and complementary creative and strategic business skill sets, will form an undeniable team and prove to be great leaders for the future of Warner Bros. Television Productions UK. We look forward to continued success across the globe with the combination of our U.S., UK and international television production businesses, including the recently acquired Eyeworks Group and the BlazHoffski Group.”

Emmerson will report to Roth on creative matters and work closely with WBTV unscripted/alternative head Mike Darnell, as Shed Media was best known for its nonfiction productions. Emmerson most recently served as CEO of Ricochet Television since January 2013.

Hungate will report to Emmerson and be responsible for the business, strategic and financial operations of the new company. She will also work closely with the division heads regarding business and operations of Wall to Wall, Twenty Twenty, Ricochet, Watershed, Renegade, Yalli and Headstrong. Hungate had previously been chief operating officer of Shed Media Group since November 2010.

Together with Emmerson, they will work closely with Ronald Goes, executive vice president and head of International Television Production, in managing the business.
